[Python] How to fix pygame error: not a file object

I'm trying to build a Python mp3 player and can't get over this error, any help is really appreciated. Here is my code:

from tkinter import *
from tkinter import filedialog
import pygame.mixer as mixer
import os

mixer.init()
root = Tk()
root.geometry("700x220")
root.title("Mp3 Player")
root.resizable(0, 0)


def play_song(song_name: StringVar, songs_list: Listbox, status: StringVar):
song_name.set(songs_list.get(ACTIVE))
mixer.music.load(songs_list.get(ACTIVE))
mixer.music.play()
status.set("MP3 PLAYING")


def stop_song(status: StringVar):
mixer.music.stop()
status.set("MP3 STOPPED")


def load(listbox):
os.chdir(filedialog.askdirectory(title="mp3 directory"))
tracks = os.listdir()
for track in tracks:
listbox.insert(END,tracks)


def pause_song(status: StringVar):
mixer.music.pause()
status.set("MP3 PAUSE")


def resume_song(status: StringVar):
mixer.music.unpause()
status.set("MP3 RESUMED")


song_frame = LabelFrame(root, text="current song", bg="LightBlue", width=400, height=80)
song_frame.place(x=0, y=0)

button_frame = LabelFrame(root, text="Control Buttons", bg="Turquoise", width=400, height=120)
button_frame.place(y=80)

listbox_frame= LabelFrame(root, text="Playlist")
listbox_frame.place(x=400, y=0, height=200, width=300)

current_song=StringVar(root, value="<Not Selected>")

song_status= StringVar(root, value="<Not Available>")

#playlist box
playlist = Listbox(listbox_frame, font=('Helvectica', 11), selectbackground="Gold")
scroll_bar = Scrollbar(listbox_frame, orient=VERTICAL)
scroll_bar.pack(side=RIGHT, fill=BOTH)

playlist.config(yscrollcommand=scroll_bar.set)
playlist.pack(fill=BOTH, padx=5, pady=5)

Label(song_frame,text="CURRENTLY PLAYING: ", bg="Lightblue", font= ("Times", 10, "bold")).place(x=5, y=20)

song_lbl= Label(song_frame, textvariable=current_song, bg="Goldenrod", font=("Times", 12), width=25)
song_lbl.place(x=150, y=20)

pause_btn = Button(button_frame, text="Pause", bg="Aqua", font=("Georgia", 13), width=7, command=lambda: pause_song(song_status))
pause_btn.place(x=15, y=10)

stop_btn= Button(button_frame, text="Stop", bg="Aqua", font=("Georgia", 13), width=7, command=lambda: stop_song(song_status))
stop_btn.place(x=105, y=10)

play_btn=Button(button_frame,text="Play", bg="Aqua", font=("Georgia", 13), width=7, command=lambda: play_song(current_song,playlist,song_status))
play_btn.place(x=195, y=10)

resume_btn= Button(button_frame, text="Resume", bg="Aqua", font=("Georgia", 13), width=7, command=lambda: resume_song(song_status))
resume_btn.place(x=285, y=10)

load_btn=Button(button_frame, text="Load Directory", bg="Aqua", font=("Georgia", 13), width=35, command=lambda: load(playlist))
load_btn.place(x=10, y=55)

Label(root, textvariable=song_status, bg="SteelBlue", font=("Time", 9), justify=LEFT).pack(side=BOTTOM, fill=X)


root.update()
root.mainloop()


This is the error I got:
